VDI2700

VDI 2700 Blatt 8
The VDI 2700 guideline is published by the Association of German Engineers as a loading guideline for various goods. It is regarded as the "state of the art" and thus provides a basis for loading and the corresponding load securing. Specifically for "load securing on road vehicles, securing of cars as well as light and heavy commercial vehicles on car transporters," the loading guideline VDI 2700 Part 8/8.1/8.2 applies. The latest revision of this guideline was only recently completed and came into effect in September 2024.
In the following we present the relevant components and interrelationships of this guideline. Basically, it is a combination of securing with wheel tie-down straps, wheel blocks and the corresponding perforated decking sheets, which serve as lashing points. However, the new guideline also includes a dynamic test of the superstructure strength of the entire vehicle.
Components of VDI 2700 8.1

Wheel tie-down straps
Essential for load securing as a central means of securing a vehicle via the wheel on a car transporter. In addition to the standard requirements that a lashing strap must fulfil, a strap controller is used in the construction of the strap, which ensures that the webbing does not touch the tyre and ensures optimal power transmission with as little friction loss as possible. The hook shapes used must be approved for the corresponding perforated decking sheets.

Wheel blocks and perforated decking sheets
Another securing device is the wheel block which must be tested for locking force and accuracy of fit in combination with the corresponding perforated decking sheets. The perforated decking sheets themselves are subject to testing of the coefficient of sliding friction of the surface. A test is also required to classify the perforated decking sheets as a lashing point. However, this requires a test of the mounted perforated decking sheet on the entire vehicle or a self-supporting perforated sheet.

Vehicle superstructure strength
The vehicle configurations of the complete vehicle must be designed for the acceleration forces occurring in accordance with DIN EN 12195-1 (in a loaded condition) and must also undergo a dynamic driving test accordingly.

Wheel tie-down straps and strap controllers according to VDI 2700 8.1
The ProLux wheel tie-down straps have been certified by the German technical inspection organisation TÜV Süd in accordance with VDI 2700 Sheet 8 ff. Accordingly, all products fulfil the newly prescribed ETA value of the lashing strap/strap controller combination of ≥ 0.5, as well as the defined pre-tensioning force (STF) of 330 daN.
The strap controllers must be designed in such a way that the strap tension is distributed as evenly as possible on both sides of the tyres during lashing. Therefore, the controller in combination with the tie-down strap must have a transmission coefficient (Eta value) over the vehicle tyres of ≥ 0.5 in the overall system.
It is important to ensure that the strap controller covers at least 180° of the tyre circumference during use so that the strap does not have contact with the tyres. For this purpose, we offer strap controllers with a length of 1100 mm, which is sufficient to cover 90% of the common wheel sizes.
Should this not be sufficient, we offer an extension that can easily be attached with a Velcro fastener.
Hook combinations for all applications
We have a variety of hook shapes and strap configurations - this is necessary to meet your exact needs!
As a general rule, the hook shape must be approved for the roadway elements (perforated decking sheets). Please note that you must therefore ensure what the correct strap configuration is for your application or for the vehicle you are using and what the vehicle manufacturer has approved.

The correct interaction is crucial
The wheel blocks and corresponding perforated decking sheets are each subject to a combined inspection. This means that each wheel block is specifically tested and approved for each individual perforated decking sheet.
For perforated metal sheets, the coefficient of friction test is decisive, in addition to the lashing point inspection. The lashing point inspection must be carried out on the perforated decking sheet in its installed state on the original vehicle, which is why in most cases this is only carried out by vehicle manufacturers.
Individual flat sheets do not have any load-bearing capacity or corresponding resistance for testing on their own – therefore, an original supporting substructure is required here, as is also used when the vehicle is put into circulation.
An exception here are sheets with a self-supporting structure, where an independent inspection can also be carried out due to the supporting design of the sheet.
